Competition Requirements
The L Prize competition requirements issued in 2008 included technical specifications for the 60-watt and PAR 38 categories. The competition requirements were developed to ensure compliance with the general requirements outlined in the 2007 energy legislation, with additional details specified for quality, performance, and mass manufacturing.
On August 3, 2011, DOE awarded the L Prize for the 60-watt incandescent replacement lamp to Philips Lighting North America. At this time DOE has closed the 60-watt category and will not accept or evaluate further entries in this category.
On January 5, 2011, DOE announced plans to modify the L Prize competition requirements for the PAR 38 category, to incorporate lessons learned from the 60-watt competition process. The PAR 38 competition is temporarily closed, and entries will not be accepted until the competition reopens.
The complete competition requirements for the 21st Century category have not yet been fully defined or published. The 21st Century category is not open for entries at this time. Necessary guidance will be announced by DOE and posted on this website in the future.
